Can you trace that with:usbdump -i usbusX -f Y -v ? What rates are supported. Can you try 48000 Hz?
44100 and 48000. The attached usbdumps are with 48000 Hz. The "1" is with 32bit audio output, the "2" with 16bit audio output.
This is what is reported in dmesg: ---snip--- uaudio0 on uhub3uaudio0: <Creative Technology SB Live 24-bit External, class 0/0, rev 1.10/1.00, addr 2> on usbus5
uaudio0: Play: 48000 Hz, 4 ch, 24-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 44100 Hz, 4 ch, 24-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 96000 Hz, 2 ch, 24-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 48000 Hz, 2 ch, 24-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 44100 Hz, 2 ch, 24-bit S-LE PCM format, 2x8ms buffer. uaudio0: No MIDI sequencer. pcm2: <USB audio> on uaudio0 uaudio0: No HID volume keys found. ---snip---As this is a 5.1 device, I would expect 6 channels, not 4 (the config descriptor dump is in my initial mail).
